Measurement of angular position using variation of magnetic field amplitude induced by the displacement of a moving magnet has been intensively developed over the last fifteen years. However, these solutions have limits in terms of angular range and temperature influence.

The technology used by Piher is only sensitive to the flux density coplanar with the IC surface. This allows to decode the absolute rotary (angular) position from 0 to 360 degrees. It enables the design of high performance non-contacting magnetic rotary position sensors for both automotive and industrial applications whithout the limitations of potentiometric solutions (wear, electrical angle...).

Piher sensors adapt to the customer´s shaft so they do not require extra-operations such as assembly of magnet & sensor unlike other solutions in the market.

In combination with the appropriate signal processing, the magnetic flux density of a small magnet (diametral magnetization) rotating above the IC can be measured in a non-contacting way. The angular information is computed from both vectorial components of the flux density (i.e. BX and BY). Then an output signal proportional to the decoded angle is produced. Our sensors do not rely on expensive bearings what affords Piher to offer the best price in the market. The output is selectable between Analog, PWM and Serial Protocol. A configurable switch ouptput is integrated within the sensor too.

Redundancy is also integrated in the circuit and furthermore you can request a dual-chip sensor for true full redundancy which comprises a dual switch output.

Unparalleled Performance and Integration.

With truly non-contacting sensing, high repeatability, low power consumption and wireless option, these sensors provide an all-in-one integrated and maintenance free solution for harsh environments.

Piher is a specialist designer and manufacturer of true non-contact absolute sensors for use in harsh environments and custom product tailoring for use on Tier One and OEM platforms including contactless magnetic technology complete sub assemblies.

MTS-360 product has been developed through the project titled “Research and development of sensors for medical devices”, co-funded by Sociedad Estatal para la Promoción y Atracción de las Inversiones Exteriores, S.A., (The State Company for the Promotion and Attraction of Foreign Investment, plc.) part of the Ministry of Economic Affairs and Competitiveness, and co-funded by European Regional Development Fund (ERDF).
